The answer to 'why is my kitchen greasy' is that a buildup of grease and oil residue is a common issue in many kitchens. This can be caused by a few different factors, including cooking methods, lack of regular cleaning, and ventilation issues.
Cooking foods with a lot of oil or fat, like frying, can leave behind a greasy film on surfaces like countertops, cabinets, and appliances. Over time, this grease can accumulate and become difficult to remove. Poor kitchen ventilation, such as an ineffective range hood, can also contribute to grease buildup by not properly removing cooking fumes.
